Hi Dragon20, Glad to hear it all worked out. This seems like a pretty nice mod. Have you noticed any change in the sound after break in? I want to ask if you got any compliments from people who didn't know about the change. Is it something that people will notice straight away?

I'm also wondering if it might be too loud for some situations. Our cars in Australia have 500cc less capacity than the US spec 328i and ours are not fitted with secondry cats - Maybe a difference, or maybe not?

The BMWPE is DEFINITELY noticeable but is never too loud unless you plant your foot. Stock 325i sounds like a hybrid.

I don't think you can rely on the pics from the catalog because they are often just illustrations and detail won't be accurate. Its better to look underneath the rear of your car to check if the pneumatic valve exists.
